Seat Adjustment:

~The Swisher ZT2452A is equipped with a 6” range sliding seat.

~Release the tension on the seat adjustment lever by pushing the tip of the lever to the left. See features section in this manual

~Using your own weight. slide the seat to the desired position

~Release the lever

Travel Reduction Adjustment: (Hand Control Levers)

~To improve the tracking of the Swisher ZT2452A the speeds of the two hydrostatic transmissions must be the same.

If one of the rear wheels needs to be increased or decreased this adjustment can be performed utilizing the control linkage assembly which is the coltrol rod that connects the handle mechanism to the hydrostatic transmission. There is one for each transmission.

~If the ZT2452A pulls to the right the left wheel will need to decrease speed and if pulling to the left the right wheel will need to decrease speed.

~To decrease the speed in one of the rear wheels lengthen the linkage assembly between that side control handle mechanism and the hydrostatic transmission. Do this be removing the hair pin from the contol handle end and disengaging the control linkage from the control handle. Loosen one of the jam nuts and by lengthening this control linkage you can decrease the speed of the hydro. Refer to the exploded view of the control mechanism on the following pages.

~Be sure the securely tighten the jam nuts against the nut coupler on the control linkage after the desired adjustment has been made. Reassemble and test. Repeat this process until the mower drives in a straight line.

Back before electricity came to rural Missouri Max Swisher was producing lawn mowers from his mother’s chicken house. Max never liked to mow grass. He installed a gearbox on his family’s lawn mower creating a self-propelled unit. By tying one end of a rope to the mower and the other end to a tree in the center of the yard the mower circled the tree. shortening the rope and guiding the mower in concentric circles. Max enjoyed relaxing under a shade tree while his invention did all the work.

Max had designed his first self-propelled rotary lawn mower to do his dirty work for him.

Neighbors noticed his new invention and began asking him to make more. Today. 60 years later. Swisher is still producing innovative lawn and garden and ATV/UTV equipment designed to give us all more “relaxing in the shade” time.

Swisher products have been featured nationally on television programs such as Regis and Kathie Lee and seen in publications like ATV Magazine. Country Journal. Popular Mechanics Magazine and others. In January 2000 Popular Mechanics Magazine named Max’s zero turning radius riding mower one of the 20th century’s top household inventions.

Swisher offers value and function in its products to meet your grounds maintenance needs.
